Floorplan 3D is a free online floor plan editor that runs entirely in your web browser. You draw your home's layout in 2D at true scale — walls, doors and windows measured in metres or feet — furnish it from a built-in library, and then step inside a 3D view of the same plan, including a first-person walkthrough with day and night lighting. There is nothing to install, no account to create, and no watermark on anything you make.
Open the 2D floor plan converter and upload a plan image (PNG or JPG) or a PDF. You can let the free AI detection draft the rooms for you — a few runs per day, no key needed — or trace the rooms manually over the image, which is always free and exact. Set the scale with two clicks on a known measurement, generate the 3D model, then adjust doors, windows and furniture in the editor. The converter overview and the step-by-step guide explain each route, including what to check in an AI draft.
Yes — the editor, the converter, furnishing, measurements and plan sharing are all free, with no sign up and no watermark. AI room detection is free on the site too, within a few runs per day per visitor; if you would rather use your own AI provider key, you can, and any per-use fee is then charged by your provider to you, never by this site. Manual tracing is always free and unlimited.
Only in your own browser, on your own device — designs are saved in the browser's local storage and are never uploaded to our servers for editing. Share links carry the plan encoded inside the link itself, so anyone who has the link can open that design. The Privacy Policy describes the optional AI detection and analytics in detail.
No. Floorplan 3D runs in the browser tab you already have open, and your design saves automatically in that browser. There are no accounts and nothing to download.
Yes — it runs in any modern browser, desktop or mobile. Precise drawing is easier with a mouse on a larger screen, but viewing, measuring and walking through a plan work fine on a phone.
